Abstract: An ultraviolet light generation target includes a light emitting layer. The light emitting layer contains a YPO4 crystal to which at least scandium (Sc) is added, and receives an electron beam to generate ultraviolet light. Further, a method of manufacturing the ultraviolet light generation target includes a first step of preparing a mixture containing yttrium (Y) oxide, Sc oxide, phosphoric acid, and a liquid, a second step of evaporating the liquid, and a third step of firing the mixture.

Abstract: A device for lighting a room is described. The device has an envelope with a transparent face, the face having an interior surface coated with a cathodoluminescent screen and a thin, reflective, conductive, anode layer. There is a broad-beam electron gun mounted directly to feedthroughs in a base of the envelope with a heated, button-on-hairpin, cathode for emitting electrons in a broad beam towards the anode, and a power supply mounted on the feedthroughs at the base of the envelope that drives the cathode to a multi-kilovolt negative voltage. A two-prong snubber serves as an anode contact to permit the power supply to drive the anode to a voltage near ground. A method of manufacture of the anode uses a single step deposition and lacquering process followed by a metallization using a conical-spiral tungsten filament coated with aluminum by a thermal spray coating process.
